WILLIAM DANIEL LLOYD, OF FISKVILLE, TEXAS.

WEEDER.

SPECIFICATION forming part'of Letters Patent No. 693,286, dated February 11, 1902. Application tiled September 14, 1901. Serial No. 75,380. (No model.)

To @ZZ whom it may concern:

Be it known that I, WILLIAM DANIEL LLOYD, a citizen of the United States, and a resident of Fiskville, in the .county of Travis and State of Texas, have invented a new and Improved Weeder, of which the following is a full, clear, and exact description.

The purpose of the invention is to provide a simple, light, and durable implement which will effeotually remove weeds, rubbish, and all foreign matter simultaneously from each side of a row or drill of corn, cotton, or other plants and direct the removedl material to the longitudinal center of the row or drill.

A further purpose ofthe invention is to construct the implement so that hoes will be given rotary reciprocating motion through gearing and cranks from the supporting- Wheels of the implement.

Another purpose ofthe invention isto provide means for normally holding the hoes from contact with the ground and for bringing one or both hoes to an engagement' with the ground, and, further, to provide independf ent driving mechanism for each hoe, and

means whereby said driving mechanisms may. be quickly and conveniently thrown into and dicate corresponding parts in all the figures.

Figure 1 is a plan View of the improved implement. Fig. 2 is a central vertical section taken practically on the line 2 2 of Fig. 1, and Fig. 3 is a verticalsection taken substantial] y on the line 3 3 of Fig. 1. v

The frame of the machine consists of two arched bars A and B, connected at the top by the inner end of the pole or tongue C.. At each end of the downwardly-extending members of the forward barA a horizontal foot 10 is formed, extending in the same direction as the body portion of the bar, and similar feet 11 are formed at the extremities of the end members of the rear bar B of the frame. Axles 12 are secured to the outer ends of the foot-sections 11 of the rear bar B, and on each axle l2asupporting-WheellSisloosely mounted. An internally-toothed ring-gear 14 is firmly secured, preferably, to the lspokes of each wheel 13 at its inner face, as is shown bestiu Figs. 2 and 3.l Bars 15 and `l6 connect the foot-sections 10 and 11 of the frame.` These bars extend in direction of thev front and rear of the implement, and the said bars 15 and 16 are bolted or otherwise attached to the said foot-sections, as is best shown in Fig. 1. Hangers 17 extend down from the under faces of the bars 15 and 16, and these hang-v ers journal shafts 18. Upon each shaft 18, between the hangers journaling the shaft, a

pinion v19 is secured. At the inner end of bed formed by the bars 15 and 16, and these plates 23 may be properly termed shifting plates, as will be hereinafter described.

Each shifting plate 23 at its forward endA passes beneath a yoke-guide 2li, secured to thebed-bars 15 and 16, near the forward ends of said bars, and each shifting plate 23 is provided with a central longitudinal slot 25, and these slots are over the space between the bed-bars 15 and 16 at the sides of the frame.

The links 22 extend reart so"A The slots 25 in the shifting plates 23are of sufficient length to extend beneath the yokeguides 24, and these guides are provided with recesses 26, (shown in Fig.'1,) the recesses registering with the slotsy 25 in the shifting plates.

Each shifting plate 23 is provided with an upwardly-extending bearing 27 at each side of the central portion of its slot 25, and in the bearings 27 of each shifting plate a shaft 29 is journaled. On each shaft 29 a gear-wheel 28 is secured, mounted to turn in the slot 25 of a shifting plate and in the space` between the bed-bars beneath the plate. In oneposition of the shifting plates the gear-wheels 28 mesh with the pinions 19 on the lower shaftslS, whereas in another position of the shifting plates the gears 28 and pinions 19 are out of contact, as is shown in Fig. 3. Each upper IOO shaft 29 is also provided with a pinion 30 at its outer end, and thus the pinions in one position of thepshifting plates engage with the teeth of the ring-gears 14 on the supportingwheels and in another position of said shifting plates the pinions 30 are carried out of engagement with the ring-gears. Vhen the pinions 30 are out of engagement with the ring-gears 14, the large gearwheels 2S on the shafts 29 are out of contact with the pinions 19 of the lower shafts 1S.

A post 31 is formed about centrally of the rear face of each foot-section of the rear memberB of the frame of the implement, and these posts receive bolts 32 or their equivalents at' their upper ends. These bolts serve to hold spring locking-tongues 34 in position on the rear portions of the shifting plates, and each locking-tongue at its free end is provided with a spur 35. These spurs are adapted to enter any one of a series of apertures or indentations 36, produced in the upper faces of the shifting plates. The spurs 35, and likewise the recesses 36, are preferably semi-ovoidal in form, so that while the spurs when in the recesses 36 will hold the shifting plates in a certain position should it be desired to change the position of the shifting plates, such change may be readily accomplished by simply forcing the plates forward or backward, and the spurs 35 will thereupon automatically ride out of the recesses 3G, in which they were seated, and will enter the neXt succeeding recesses. The movement of the shifting plates is accomplished through the medium of handles 37, and these handles are pivoted at the rear ends of tongue-sections 36, forming rear continuations of the shifting plates. It may be here remarked that the recesses 3G above referred to are produced in the upper faces of these tongue-sections. The connection between the tongue-sections of the shifting plates and the handles 37 is accomplished through the medium of pivot-pins 38, and the lower ends of the handles 37 are pivotally attached to the rear portions of horizontal brackets 39, which are secured in any suitable or approved manner to the under faces of the foot-sections 1l of the rear member B of the frame.

Arms 40 are attached to the inner faces of the upright members of the forward and rear sections A and B of the frame. These arms extend beyond the front and rear of the frame and at their forward ends carry draft rings or links 41, while the rear portions of the arms 40 are slightly contracted or brought nearer together than at their forward portions, as is shown at 42 in Fig. 1.

Links 43 (shown in Fig. 2) are pivotally attached to the inner face of the upright members of the rear section B of the frame, the said links being capable of up-and-down movement, and these links extend rearward and are bifurcated at their rear ends. The

bifurcated portions of the links 43 receive the forward ends of handles 44, whose rear portions are upwardly and rearwardly curved. The body portions of the handles 44 are normally heldin a horizontal position by tension devices 45 of any description attached to the handles near their rear curved portions and to the rear ends of the arms 40, as is shown in Figs. 1 and 2. Stirrups 48 are pivotally attached to the rear ends of the arms 40, and these stirrups are adapted to hold the handles 44 in their upper position and the hoes, to be described, off of the ground, as is shown in positive lines in Fig. 2. When the hoes are to be forced down to the ground, the handles are lifted from the stirrups and carried inward to disengage said handles from the stirrups, whereupon the stirrups when the handles are depressed will ride on the top portions of the handles and arein position for use when required. It will be observed that the handles are capable of vertical movement through the medium of the links 43 and of lateral movement by reason of their pivotal connection with said links.

Beams 49 are pivotally attached at their forward ends to the links 22, connected with the crank-disks 20. The forward ends ofthe beams 49 extend within the bifurcated rear ends of the said links, so that the links have Vertical movement with the crank-pins on the disks 20, and the beams 49 have lateral movement on the links. These beams are curved downward and rearward at their rear ends, and their rear extremities are flattened at the front and are twisted inward, so that the rear extremities of the said beams 49 stand at angles to each other, as is shown in Fig. 1. A hoe 50 of any description is secured to the flattened rear extremity of each beam 49, and consequently these hoes stand at angles to each other, sloping outwardly in opposite directions. In fact, these hoes slope from the drill in order to throw the weeds to the center of the row or drill, as is clearly shown in Fig. l. The beams 49 are connected with the handles 44 by means of links 51, (shown best in Fig. 2,) so that when the handles 44 are pressed downward the beams 49 are also carried downward and the hoes are brought in engagement with the ground; but when the handles 44 are relieved from downward pressure the tension devices 45 restore them to their normal position and raise the hoes from the ground.

It will be observed from the construction described that the hoes have a rotary reciprocating motion or a motion which corre spends to that imparted to a hoe when used by hand and that the Shanks of the hoes operate together, as the wrist-pins 21 on the disks 2O are in horizontal alinement. It will also be observed that either hoe may be brought into operation or carried out of operation,as desired, and that both hoes may beA made to operate simultaneously.

Having thus described my invention, I claim as new and desire to secure by Letters Patentn IOO IIO
